This nationwide study of the status and organization of vocational education at the state level was conducted to secure consistent and valid statistical data useful for the study of possible relationships among state-level organization, state-level administration, and the operations of programs in vocational-technical education. Data for the 50 states and Puerto Rico were compiled from sources such as recent state plans, state legal codes, organizational charts, personnel directories, and the U.S. Office of Education statistical reports for 1966-67. Summaries of data for each date were compiled for sub-topics of organization, administration and program operation and are included in the document. Appendixes include research methods and data sources, and tabulations of data for the study of organization for the administration of vocational-technical education, by states. A conclusion of the study was that the problems resulting from the current trends toward the separation of state-level administration of secondary and postsecondary vocational-technical education, may be expected to become even more complex. Volumes II and III of this study are available as VT 008 831 and VT 008 832 respectively. (CH)
